【Abstract】 ABSMS is a software system developed especially for the modelling ofthe auto body. This paper introduces its theoretical basis and main func-tions. Due to the partial property, visual convenince, convexity of B-sp-line curve, and the application of multiple knot method, the system hasrather strong functions of surface modelling.更多还原
